Have done a bunch of roofs from the ground with an X-Jet.. or lets say applied the chemicals that way. I have yet to have a roof where the shingles didn't need to be washed.. ie, up close and personal attention with a couple hundred psi. Do you guys wash your roofs or just rinse them from the ground? I don't know if this is a northeast thing or perhaps just the jobs we have done but I have yet to get a shoot and rinse job.
That's because you're using an X-jet- not enough chems are hitting the roof.
If you're really gonna do a roof here and there I'll loan you the $129 for a Delevan.
